Abstract

Dispositif appliqué à la régulation du débit d'air circulant dans un arbre rotatif (10) d'une turbomachine comportant au moins un orifice (12) le traversant pour le passage de l'air. Le dispositif comporte au moins une soupape d'obturation (14) de l'orifice (12) qui est solidaire d'une lame déformable (16) à comportement bilinéaire, la lame (16) étant fixée sur l'arbre (10) et apte à se déformer sous l'effet de la force centrifuge résultant de la rotation de l'arbre de sorte que la soupape (14) est apte à prendre deux positions différentes selon le régime de rotation de l'arbre ; une position dans laquelle elle obture l'orifice (12) et une autre position dans laquelle elle libère l'orifice pour permettre le passage de l'air.

Device applied to the regulation of the air flow circulating in a rotary shaft (10) of a turbomachine having at least one orifice (12) passing through it for the passage of air. The device comprises at least one shutter valve (14) of the orifice (12) which is integral with a deformable blade (16) with bilinear behavior, the blade (16) being fixed on the shaft (10) and able to deform under the effect of the centrifugal force resulting from the rotation of the shaft so that the valve (14) is adapted to take two different positions according to the rotational speed of the shaft; a position in which it closes the orifice (12) and another position in which it releases the orifice to allow the passage of air.
